The Effect of Certain Rootstocks on the Grape Cultivar 'Pusa Urvashi' (Vitis vinifera L.)

A study entailing four rootstocks was designed under glasshouse conditions to select the most suitable rootstock for the grape cultivar Pusa Urvashi on the basis of growth, physiological, biochemical, and nutrient changes brought about by stionic influence, which may have implications on vigor and stress tolerance of the composite plant. The performance of 'Pusa Urvashi' scions on four rootstocks was compared with its performance when grafted on its own roots. The foliar tissue analysis revealed that the rootstocks induced alteration in different biochemicals in the grafted vines. Compared to 'Pusa Urvashi' grafted on itself, the grafted rootstock-derived plants exhibited improved physiological and nutrient status. Rootstocks also showed satisfactory graft healing and compatibilty under glasshouse conditions.
